Looks like there is a scroll position change as you switch tabs.
This looks like Issue 908796, which was merged into M72 this morning.  Can you verify whether this still reproduces with the next beta?

Marking as WontFix.  The fix for Issue 908796 was reverted, as it introduced  Issue 920655 .  After talking with Kariah, we decided that  Issue 920655  is worse than this bug, so we're intentionally shipping M72 with this bug.
